Description
Technical Field
The invention relates to the technical field of grassland treatment, in particular to a water storage and grass enrichment method for bottom ploughing of a grassland interval soil layer without disorder.
Background
It is known that the grassland area of China is 432 hundred million hectares, occupies 13 percent of the grassland area of the world, is second only to Australia, and is the second grassland big country of the world. The grassland resources in China mainly comprise northern grassland, southern grassland hillside, coastal mudflat, wetland, natural grassland in agricultural areas and the like, such as famous Xinjiang Ili-Larita grassland, inner Mongolia stannum Guo Lei grassland, inner Mongolia Hulunebel grassland and inner Mongolia stannum Haote grassland and the like, and the grassland is litmus, in the wild, and the windblown grass is low in the cattle and sheep, so that the grassland makes great contribution to the animal husbandry in China and is the place where many civilians are facing the home.
Under the large background of global climate change and strong drive of human factors, the structure of a grassland ecological system gradually tends to be simplified and the function tends to be weakened. Grassland deterioration is caused by a variety of factors, including natural factors (such as drought, wind erosion, insect and mouse damage, etc.) and artificial factors (such as excessive grazing, heavy mowing, excessive reclamation, digging, etc.). In recent years, due to the dual role of human and natural factors, the grass land degeneration is increasingly serious, and the continuance, stability, coordinated development and regional economic sustainable development of the grass land animal husbandry are directly threatened. Even more serious problems arise in northern grassland areas: treating three types of grassland; the three transformation of grassland refers to degeneration, desertification and alkalization. Due to excessive grazing and grassland resource use and aggravation of desertification process in northwest regions, the grassland area is continuously reduced, and the sand storm becomes an environmental pronoun in the northern regions; today, people cannot imagine a picture like a vault and a field, and more difficult to imagine, if the water and soil conservation in a grassland area cannot be effectively improved, what situation appears after 10 years. In order to maintain the healthy development of animal husbandry, it is necessary to search for an improved construction scheme of the grassland and to perform recovery and treatment on the grassland.
Researches show that with the aggravation of the degradation degree of the grassland, a large amount of toxic weeds appear, and the high-quality pasture is obviously reduced. The soil environment characteristics can also change along with the change of the overground vegetation, and further cause the change of the number of soil microorganisms. With the increasing of the deterioration degree of the grassland, the contents of soil organic matters, quick-acting phosphorus and quick-acting potassium, the soil firmness and the soil humidity are all reduced, and soil nutrients cannot meet the requirements of normal growth and development of plants under the extreme deterioration condition. However, excessive fertilization causes soil hardening, and is effective to the growth of pasture grass in a short period and unfavorable to the long-term excessive use. In arid and rainless areas, plants are usually subjected to a plurality of operation procedures such as plowing, sowing, pressing and the like when being planted, soil wind erosion and water erosion are easily caused when grasslands are plowed, if planting fails or planted pasture varieties cannot safely live through the winter, the grasslands are more easily subjected to wind erosion and water erosion in the soil in the second year, the ecological environment of the grasslands is damaged, sand storm is formed in the spring, soil particles with the diameter of less than 0.1 mm are blown away by strong wind, the fine particles are originally fertile parts in the soil, and the content of organic matters and nitrogen elements is twice of that of the original soil.
Therefore, there is a need to develop a method for enlarging grassland with low cost and significant effect by comprehensively considering the current situation of grassland, reducing or relieving the growth restriction factors of plants, so as to restore the ecological status of grassland and maintain the continuous and healthy development of grassland animal husbandry.
